SPECIFICATION forming part of Letters Patent No. 740,603, dated October6, 1903. Application-filed November 11,1902. Seria-l No. 130.905.(Noimodel.)

To all whom it may concern,.-

Be it known that I, ISAACv K. STORMS, a c itizen of the United States,and a resident of Duluth, in the county of St. Louis and State ofMinnesota., have invented certain new and useful Improvements inBob-Sleighs, of which the following is a specification.

My invention relates to bob-sleighs, and has for its object to provide adevice of this character that will overcome to a great extent the jarsto which they are subjected by swivelly mounting the runners so thatthey will dodge obstructions as well as accommodate themselves tounevennesses in the road.

In logging through woodland, hauling over rough farm-land, as well asteaming over coun-,

try roads many obstructions-such as stones, stumps, roots, d:c.-areliable to be encountered, and also ruts and mounds, so that aset ofrunners that are flexibly mounted so as to dodge around any obstructionsthat may be encountered or accommodatethemselves to surface unevennesseswould not only add to the safe carrying of the load, but also to thelife of the structure.

The advantages of my invention will fully appear hereinafter and byreference to the accompanying drawings, in which v Figure l is aperspective view of a pair of runners embodying my invention; Fig. 2, anenlarged side ,view of a portion of a runner, and FigA 3 a cross-sectionthrough one of the runners.

Referring to the drawings, in which similar reference charactersindicate corresponding parts throughout the several views, A representsthe runners shodvwith the iron bands B.

C represents the kneefpedestals, which are secured to the top of therunners A by means of bolts D, passing through ears c, extendingdownward from the pedestals C, while E representsthe pivot-pins securedto the pedestals C by means of nuts F, secured on a threaded extension eon said pins E, said bolts being countersunk in the top of runners A, asshown in Fig. 3. The central portion of pins E are made larger indiameter than the ends, as shown at G, the bottoms of said centralportions resting on the pedestals C, while the upper end forms ashoulder to hold the free end of strengthening-braces H, secured to thetop of runners A, in the desiredV position.

I represents the bolster connecting the pins E, .I being the holes toreceive said pins. K represents the hole to 'receive the king-pin tosecure the sleigh-body to the runners. The holes .I and K are madeconsiderably larger than the pins E and the king-pin, (not shown,) so asto permit side play of the runners in passing over unevennesses in theroad.

Lrepresenl-s the draft-chain secured over hooks M on the top of therunners, and N al spreader-bar pivotally connected to the front of therunnersA bymeans of eyeboltsO, passing through said runners.

Having thus described my invention, what I claim is- Y l. A knee forbob-sleighs consisting of a pedestal resting on the top of the runner,downwardly-extending ears resting against the sides of the runner, boltspassing transversely through the runner and said ears, a

pin secured through the top of said pedestalhaving an enlarged centralportion resting on said pedestal, and a brace secured to the runner andover said pin, substantially as shown and described.

2. In a bob-sleigh, the combination with runners, suitable draftconnections, and a pivoted spreader-bar, of knees consisting ofpedestals resting on the top of said runners, downwardly-projecting earsthrough which pass transverse securing-bolts, pins secured through thetop of said pedestals, and brace vrods secured to the top of saidrunners and loosely fitting on the pins aforesaid, and a bolster looselymounted on said pins, substantially as shown and described.

3. In a bob-sleigh, the combination of the runners, draft connections,and a pivoted spreaderbar, of knees consisting of pedestais resting onthe top of said runners, downwardlyextending ears through which passtransverse securing-bolts, pins secured through the top of saidpedestals having en larged central portions resting on the top thereof,and brace-rods of dat metal secured at one end to the runners forward ofthe pins and having their other ends provided with an opening to receivethe top of thepins, and a bolster having openings to receive said pins,said openings being appreciably larger in diameter than the pins,substantially as shown and described.

4. In a bob-sleigh, the combination of independently-movable runners, adraft-chain secured to both runners,a spreader-bar connected by eyeboltsto the front of said runners, knees secured through the sides of therunners, and a bolster pivotally connecting said knees, substantially asshown and described.

5. In a bob-sleigh, the combination with independently-movable runners,a draft-chain secured to both runners, a spreader-bar connected byeyebolts to the front of said runners, of knees consisting of pedestalsresting on the top of said runners, downwardly-projecting ears resting`against the sides of said runners,transverse bolts secured through saidears and runners', and pins secured through the top of said pedestals,and a bolster loosely mounted on said pins, substantially as shown anddescribed.

G. A sleigh-knee comprising a pedestal, downwardly-projeoting earsthereon to fit on each side of a sleigh-runner, bolts passing throughsaid ears and the runner, a pivot-pin secured to said pedestal having anenlarged -portion next to said pedestal, and a strengthening-bracesecured to the runner and having a hole in its free end through whichthe pivotpin extends', substantially as shown and described.

7. A sleighknee comprising a pedestal,

downwardly-projecting ears thereon to t onv In testimony whereof Iheretoafiix my signature in the presence of two Witnesses.
